Outdoor Exposure

Weathering Resistance and Outdoor Exposure

Should the access doors be installed outside the building, the following points should be taken into consideration:

Install the access doors in the least exposed areas.

Install the access doors in areas where rain water cannot accumulate (not on top of rectangular ducts for instance).

The red knobs will not corrode but may discolor and become brittle over time. Metal knobs could also be used, although the risk of corrosion is more important (please refer to the additional information ZI-101).

Choose a gasket with higher UV and ozone resistances, such as the self-adhesive rubber edge molding (SKK).

Galvanized access doors can also be ordered with a thicker zinc coating (≈ 275 g/m2). Minimum order quantities and longer lead times must be expected.
